AI Technical Summary
Technical Problem
The existing fosfomycin tromethamine reaction vessel has low heating efficiency and uneven heating, which cannot meet the preparation requirements.
Method used
Several partition plates are installed in the jacket of the reaction vessel to form multiple cavities. The reaction vessel is heated by countercurrent flow through two inlets and outlets, which are connected by arc-shaped guide pipes and flanges to ensure the efficiency of medium flow and the uniformity of heat transfer.
Benefits of technology
This improves heating efficiency and uniformity, ensures the stability of the reaction temperature, and meets the preparation requirements of fosfomycin tromethamine.
